Apparently marketers decided to make fun of technically illiterate buyers of this "miracle of technology".

Well, firstly, Lenovo is again deliberately lying in psref about laptop support for 8k@60Hz resolution on the HDMI port, although any adequate person with basic knowledge in arithmetic can easily calculate, knowing the HDMI 2.1 bandwidth of 42Gb/s (excluding overhead traffic) that 7680x4320x24(bit)x60 in 4:4:4 lossless mode requires at least 48Gbps of pure data excluding service traffic. Not to mention 30bit (HDR), where you need even more... Support is only provided with lossy DSC compression, but this is not a monitor mode.
8k@60Hz at 4:4:4 lossless at 24 bit only supports full Display Port 2.0 (4 lanes x in UHBR20 mode). But this is not here, so the laptop does not support lossless 8k mode for monitors. Movie/TV only.

The Extreme prefix should mean that all the hardware works, at least, at the limit of its performance, according to the specification and even better! But what do we see in reality? Let's start...
The processor does not even reach the typical PL2 level of 115W according to the Intel datasheet for 12700H. But this is the "Extreme" version of the laptop, right? So the owner has the right to expect at least 130-150W per impulse(turbo) mode, not even the typical 115W from Intel is not used. But it is a fail, as it does not even compare with some ordinary laptops...
Go ahead, the screen is only 60Hz, although 4k@120Hz screens have been around for a long time – owner might use 120Hz from psu and 60 from battery. Here, however, for some reason, a touchscreen in 16" is attached, apparently this limited the developers. But why?
Next, we move on to RAM. Well, it's okay that it's single-channel (unlike the author of the review, the owner, of course, will immediately buy a second 32GB memory plank, although Lenovo's greed is simply amazing at a price of 3500 euros and a penny cost of 64GB DDR5 4800 - it would be better if they immediately soldered LPDDR5 6000, which was promised in another laptop, namely "Lenovo Yoga Slim 7i Pro X" (see newest review), where even with the LPDDR5 5200 in reality (yes, yes, Lenovo simply cheated buyers here in psref for it), where the memory obviously works almost 2 times faster in dual-channel mode, which is clear you can see by the speed of the memory in the "Extreme" version in single-channel mode - it is enough to multiply the speed in single-channel by 2 times in the mind... Those, a laptop for 1150 euros from Lenovo turned out to be more than 1.5 times faster in terms of speed of ram. It turns out that the "Pro" version is cooler than the "Extreme", Lenovo? Is it okay, marketers?
We go further, picking substances "Extreme" from Lenovo. We look at the exhaust temperature - it again exceeds 50C and the exhaust definitely goes straight to the screen. How long will the panel electronics(limited for max 50-55C) last under such loads and temperatures above 50C, Lenovo? Here it is definitely an Extreme version - the probability of being left without a screen is maximum, with such prolonged loads and temperatures!
Now let's move to the videochip from NVidia. What we see in TDP is 95W, although in Legions 130-140. It is obvious that even up to a certain norm it falls short, not to mention the "Extreme" version.
Maybe it is "extremely" quiet, therefore, with an average load? Again, the owner is waiting for a complete fail. See newest review about notebookcheck.net/The-fastest-Core-i7-12700H-laptop-you-can-buy-Lenovo-Legion-5-15IAH7H-review.669755.0.html
Only 29.3dB@103W(L5)...vs...46dB@138W... 2.4kg vs. 2.1kg...
Every +6dB is twice as loud. Thus, the cheap(and faster) Legion 5 is about 5 times quieter according review, while consuming only 27% less in an "average" load. So which model do we really have "Extreme" in a good way and a bad way? Extreme noise? Oh, yes...
Maybe it consumes extremely little and therefore with extremely long battery life? And here is a fail.
Lenovo - please remove "Extreme" from the name, do not disgrace yourself. There is nothing "Extreme" here, because of which someone will reach for their wallet to shell out as much as 3500 euros. Well, maybe 1500...then it's ok for buy.
